Please refer to FIG. 2, an embodiment of the present application also provides an electronic device 100.

The control method of the electronic device 100 in the embodiment of the present application can be implemented by the electronic device 100 in the embodiment of the present application. For example, the front color temperature sensor 10 can be used to execute the method in 01, the rear color temperature sensor 20 can be used to execute the method in 02, and the processor 30 can be used to execute the methods in 03 and 04.

The rear color temperature sensor 20 may be used to obtain the rear light parameters of the ambient light. The processor 30 may be used to determine the fusion light parameter according to the front light parameter and the rear light parameter, and to control the electronic device 100 according to the fusion light parameter.

The electronic device 100 and the control method thereof according to the embodiment of the present application can accurately determine the fusion light parameters according to the front light parameters acquired by the front color temperature sensor 10 and the rear light parameters acquired by the rear color temperature sensor 20, and thus can accurately determine the fusion light parameters according to the fusion light parameters To control the electronic device 100, the user experience is better.

Specifically, referring to FIG. 2, the electronic device 100 may be a mobile phone, a tablet computer, a notebook computer, a smart bracelet, a smart watch, etc. The embodiments of the present application are described by taking the electronic device 100 as a mobile phone as an example. It can be understood that the specific form of the electronic device 100 may be other, which is not limited here.

The electronic device 100 is provided with a front color temperature sensor 10 and a rear color temperature sensor 20. It can be understood that the color temperature sensor is used to detect the illuminance value and color temperature value of the ambient light. The color temperature sensor usually has multiple light sensing channels such as R\G\B\Clear. The R\G\B\Clear light sensing channel can respectively produce photoelectric response to the red light, green light, blue light and visible light in the ambient light. The analog-to-digital conversion obtains the value of the analog-to-digital converter of each channel, and the illuminance value and color temperature value of the ambient light can be obtained by performing corresponding operations on the values of the multiple-channel analog-to-digital converter.

Please refer to FIGS. 2 and 3, the electronic device 100 may further include a housing 40. The casing 40 includes a front 41 and a back 42 opposite to each other. The front 41 is used to install the display 50. The front color temperature sensor 10 is arranged on the front surface 41.

The rear color temperature sensor 20 is used to detect the illuminance value and the color temperature value on the side opposite to the display screen 50.

Please refer to Figures 4 and 5. However, the current color temperature sensor cannot accurately detect light parameters in certain specific scenes. The premise that the color temperature sensor can obtain a more accurate color temperature value is that the direct light emitted by the external light source 200 can enter the color temperature sensor more, instead of all the reflected light entering the color temperature sensor. It can be understood that since objects have various colors, the reflectance of objects of various colors to different wavelengths is different, which results in inaccurate color temperature detection when all reflected light enters the color temperature sensor. Both the front color temperature sensor 10 or the rear color temperature sensor 20 alone cannot accurately detect the color temperature in certain scenarios. For example, please refer to FIG. 4. When the light source 200 is above the back 42 of the electronic device 100, if the front When the color temperature sensor 10 detects the color temperature, the direct light emitted by the light source 200 cannot enter the front color temperature sensor 10, and basically reflected light enters the front color temperature sensor 10, resulting in the inability to accurately detect the color temperature. Similarly, referring to FIG. 5, when the light source 200 is above the front 41 of the electronic device 100, if the color temperature is detected by the rear color temperature sensor 20, the direct light emitted by the light source 200 cannot enter the rear color temperature sensor 20, basically The reflected light enters the rear color temperature sensor 20, which makes it impossible to accurately detect the color temperature.

The electronic device 100 of the embodiment of the present application is provided with a front color temperature sensor 10 and a rear color temperature sensor 20 on the front 41 and the back 42 respectively, and the front light parameters obtained by the front color temperature sensor 10 and the rear color temperature sensor 20 obtained by the rear The light parameters determine the fusion light parameters, which avoids the detection caused by the color temperature sensor cannot receive the direct light emitted by the light source 200 (that is, all reflected light enters the color temperature sensor) when the front color temperature sensor 10 or the rear color temperature sensor 20 are separately set The problem of inaccurate color temperature value makes the detected color temperature value more accurate, and the electronic device 100 can be controlled more accurately.

The front light parameter includes a front illuminance value and/or a front color temperature value. That is to say, the front light parameter includes the front illuminance value, or the front light parameter includes the front color temperature value, or the front light parameter includes the front illuminance value and the front color temperature value. The rear light parameter includes a rear illuminance value and/or a rear color temperature value. In other words, the rear light parameter includes a rear illuminance value, or the rear light parameter includes a rear color temperature value, or the rear light parameter includes a rear illuminance value and a rear color temperature value. The fusion light parameter includes a fusion illuminance value and/or a fusion color temperature value. That is to say, the fusion light parameter includes the fusion illuminance value, or the fusion light parameter includes the fusion color temperature value, or the fusion light parameter includes the fusion illuminance value and the fusion color temperature value.

Determining the fusion light parameters according to the front light parameters and the rear light parameters can be: determining at least one of the fusion illuminance value and the fusion color temperature value according to the front illuminance value and the rear illuminance value, or according to the front color temperature value and the rear color temperature The value determines at least one of the fusion illuminance value and the fusion color temperature value, or determines at least one of the fusion illuminance value and the fusion color temperature value according to the front illuminance value, the front color temperature value, the rear illuminance value, and the rear color temperature value.

Controlling the electronic device 100 according to the fusion light parameter may be: controlling the electronic device 100 according to the fusion illuminance value, or controlling the electronic device 100 according to the fusion color temperature value, or controlling the electronic device 100 according to the fusion illuminance value and the fusion color temperature value. Referring to FIG. 3, controlling the electronic device 100 according to the fusion light parameter may also be: controlling the display state of the display screen 50 according to the fusion light parameter, or assisting the camera module 70 to perform white balance processing.

Please refer to FIG. 6. In some embodiments, the front light parameters include a front illuminance value and a front color temperature value. The rear light parameters include the rear illuminance value and the rear color temperature value. Determine the fusion light parameters (ie 03) according to the front light parameters and the rear light parameters, including:

031: Determine the fusion light parameter according to the front illuminance value and the rear illuminance value, the fusion light parameter includes the fusion illuminance value and/or the fusion color temperature value;

Control the electronic device 100 (ie 04) according to the fusion light parameters, including:

041: Control the electronic device 100 according to the fusion illuminance value and/or the fusion color temperature value.

In some embodiments, the processor 30 may be used to execute the methods in 031 and 041.

That is to say, the processor 30 may be used to determine the fusion light parameter according to the front illuminance value and the post illuminance value, the fusion light parameter includes the fusion illuminance value and/or the fusion color temperature value; and according to the fusion illuminance value and/or the fusion The color temperature value controls the electronic device 100.

Specifically, when the direct light emitted by the light source 200 enters the front color temperature sensor 10 or enters the rear color temperature sensor 20, the front illuminance value detected by the front color temperature sensor 10 and the rear color temperature sensor 20 will be detected. The post-illumination value of the camera is quite different. Therefore, the processor 30 determines the fusion light parameters according to the front illuminance value and the rear illuminance value, and can more accurately determine whether the direct light emitted by the light source 200 enters the front color temperature sensor 10 or the rear color temperature sensor 20, thereby Better to choose between the front light parameters and the rear light parameters to determine the fusion light parameters.

Determining the fusion light parameters according to the front light parameters and the rear light parameters, and controlling the electronic device 100 according to the fusion illuminance value and/or the fusion color temperature value can be: ①Determine the fusion illuminance value according to the front illuminance value and the rear illuminance value, according to The fusion illuminance value controls the electronic device 100. For example, if the front illuminance value is 300lx, the front color temperature value is 5000K, the rear illuminance value is 30lx, and the rear color temperature value is 2000K, the processor 30 determines the fusion illuminance according to the front illuminance value of 300lx and the rear illuminance value of 30lx The value is 300lx, and the electronic device 100 is controlled according to the fused illuminance value of 300lx. ② Determine the fusion color temperature value according to the front illuminance value and the post illuminance value, and control the electronic device 100 according to the fusion color temperature value. For example, if the front illuminance value is 20lx, the front color temperature value is 2000K, the rear illuminance value is 100lx, and the rear color temperature value is 6000K, the processor 30 determines the fusion color temperature value according to the front illuminance value 20lx and the rear illuminance value 100lx It is 6000K, and the electronic device 100 is controlled according to the fusion color temperature value of 6000K. ③ Determine the fusion illuminance value and the fusion color temperature value according to the front illuminance value and the post illuminance value, and control the electronic device 100 according to the fusion illuminance value and the fusion color temperature value. For example, if the front illuminance value is 25lx, the front color temperature value is 3000K, the rear illuminance value is 120lx, and the rear color temperature value is 6000K, the processor 30 determines the fusion illuminance value according to the front illuminance value 25lx and the rear illuminance value 120lx It is 120lx and the blended color temperature value is 6000K, and the electronic device 100 is controlled according to the blended illuminance value of 120lx and the blended color temperature value of 6000K.

Referring to FIG. 7, in some embodiments, the method for determining the fusion light parameter (ie 031) according to the front illuminance value and the rear illuminance value includes:

0311: When the current illuminance value is greater than the predetermined multiple of the rear illuminance value, the front illuminance value is used as the fused illuminance value, and the front color temperature value is used as the fused color temperature value;

0312: When the rear illuminance value is greater than the pre-illumination value of a predetermined multiple, the rear illuminance value is used as the fused illuminance value, and the rear color temperature value is used as the fused color temperature value.

Referring to FIG. 2, in some embodiments, the processor 30 may be used to execute the methods in 0311 and 0312.

That is to say, the processor 30 can be used to: when the front illuminance value is greater than a predetermined multiple of the rear illuminance value, the front illuminance value is used as the fused illuminance value, and the front color temperature value is used as the fused color temperature value; When the illuminance value is greater than the front illuminance value of a predetermined multiple, the post illuminance value is used as the fused illuminance value, and the post color temperature value is used as the fused color temperature value.

Specifically, the predetermined multiple may be any value greater than one. When the current illuminance value is greater than the rear illuminance value of a predetermined multiple, it indicates that the direct light received by the front color temperature sensor 10 is far more than the direct light received by the rear color temperature sensor 20; when the rear illuminance value is greater than the predetermined multiple The front illuminance value indicates that the direct light received by the rear color temperature sensor 20 is far more than the direct light received by the front color temperature sensor 10 at this time. Therefore, when the current illuminance value is greater than the rear illuminance value of a predetermined multiple, the illuminance value and color temperature value detected by the front color temperature sensor 10 are selected, the front illuminance value is used as the fused illuminance value, and the front color temperature value is used as the fused color temperature value; When the post-illuminance value is greater than the pre-illumination value of a predetermined multiple, the illuminance value and color temperature value detected by the post-color temperature sensor 20 are selected, the post-illuminance value is used as the fusion illuminance value, and the post-color temperature value is used as the fusion color temperature value.

The electronic device 100 of the embodiment of the present application uses the processor 30 to compare the magnitude of the front illuminance value and the rear illuminance value, thereby determining the fusion illuminance value and the fusion color temperature value, and can accurately determine the fusion light parameter, so as to be based on the fusion light parameter To control the electronic device 100, the user experience is better.

In one example, the predetermined multiple is 2 times. Assuming that the front illuminance value is Lux1, the front color temperature value is CCT1, the rear illuminance value is Lux2, and the rear color temperature value is CCT2, if Lux1>2*Lux2, it indicates that the front color temperature sensor 10 is facing the light source 200, and the front The direct light received by the color temperature sensor 10 is stronger and more than the direct light received by the rear color temperature sensor 20, the front illuminance value Lux1 is used as the fused illuminance value Lux, and the front color temperature value CCT1 is used as the fused color temperature value CCT, namely Lux=Lux1, CCT=CCT1, so that the electronic device 100 is controlled according to the fused illuminance value Lux and the fused color temperature value CCT. If Lux2>2*Lux1, it indicates that the rear color temperature sensor 20 faces the light source 200 at this time, and the direct light received by the rear color temperature sensor 20 is stronger and more direct than the direct light received by the front color temperature sensor 10. The illuminance value Lux2 is used as the fused illuminance value Lux, and the post color temperature value CCT2 is used as the fused color temperature value CCT, that is, Lux=Lux2, CCT=CCT2, thereby controlling the electronic device 100 according to the fused illuminance value Lux and the fused color temperature value CCT.

Of course, in other embodiments, the predetermined multiple may also be 3 times, 4 times, 5 times, etc., and when the front illuminance value Lux1 is greater than 3 times, 4 times, or 5 times the rear illuminance value Lux2, the front illuminance The value Lux1 is used as the fusion illuminance value Lux, and the front color temperature value CCT1 is used as the fusion color temperature value CCT; when the rear illuminance value Lux2 is greater than 3, 4, or 5 times the front illuminance value Lux1, the rear illuminance value Lux2 is used as the fusion The illuminance value Lux and the post-color temperature value CCT2 are used as the fusion color temperature value CCT.

Referring to FIG. 8 and FIG. 9, there are two scenarios in the daily use scene of the electronic device 100 as shown in the figure. Whether it is a solar light source or various artificial light sources, the light source 200 is usually located above the electronic device 100. Therefore, in FIG. 8, the front color temperature sensor 10 can more easily receive the light emitted by the light source 200; in FIG. 9, the rear color temperature sensor 20 can more easily receive the light emitted by the light source 200. However, in these two cases, if the data detected by the front color temperature sensor 10 and the rear color temperature sensor 20 are inconsistent, for example, the front illuminance value is not greater than a predetermined multiple of the rear illuminance value, and the rear illuminance value is not greater than If the pre-illuminance value is a predetermined multiple, the processor 30 can determine the fusion light parameter according to the posture information of the electronic device 100 obtained by the posture sensor 60, so as to control the electronic device 100.

Please refer to FIG. 2 and FIG. 10. In some embodiments, the electronic device 100 further includes an attitude sensor 60. Control methods also include:

05: Obtain the attitude information of the electronic device 100 through the attitude sensor 60;

06: When the front illuminance value is not greater than the predetermined multiple of the rear illuminance value, and the rear illuminance value is not greater than the predetermined multiple of the front illuminance value, the fusion light parameter is determined according to the posture information.

Referring to FIG. 2, in some embodiments, the electronic device 100 further includes an attitude sensor 60. The attitude sensor 60 can be used to execute the method in 05, and the processor 30 can be used to execute the method in 06.

In other words, the posture sensor 60 can be used to obtain posture information of the electronic device 100. The processor 30 may be configured to determine the fusion light parameter according to the posture information when the front illuminance value is not greater than the predetermined multiple of the post illuminance value and the rear illuminance value is not greater than the predetermined multiple of the front illuminance value.

Specifically, still taking the predetermined multiple of 2 times as an example, suppose the front illuminance value is Lux1, the front color temperature value is CCT1, the rear illuminance value is Lux2, and the rear color temperature value is CCT2. If Lux1≯2*Lux2 and Lux2 ≯2*Lux1, at this time, the fusion light parameter is determined according to the posture information of the electronic device 100 obtained by the posture sensor 60.

The attitude sensor 60 may be a gravity sensor, a gyroscope, or other sensors. The attitude sensor 60 is installed inside the electronic device 100, and specifically may be located on the main board of the electronic device 100. The posture information of the electronic device 100 includes the inclination angle of the electronic device 100.

Referring to FIG. 12, when the electronic device 100 rotates counterclockwise by the angle θ, the posture information of the electronic device 100 is the inclination angle -θ° (shown in the left diagram of FIG. 12). The electronic device 100 of the embodiment of the present application obtains the posture information of the electronic device 100 by using the posture sensor 60, and the processor 30 determines the fusion light parameter according to the obtained posture information, and then controls the electronic device 100 more accurately according to the fusion light parameter.

Referring to FIG. 13, in some embodiments, the fusion light parameter (ie 06) is determined according to the posture information, including:

061: When the posture information acquired by the posture sensor 60 meets the predetermined condition, the processor 30 uses the front illuminance value as the fused illuminance value, and the front color temperature value as the fused color temperature value;

062: When the posture information acquired by the posture sensor 60 does not meet the predetermined condition, the post-illumination value is used as the fused illuminance value, and the processor 30 uses the post-color temperature value as the fused color temperature value.

Referring to FIG. 2, in some embodiments, the processor 30 may be used to execute the methods in 061 and 062.

In other words, the processor 30 can be used to: when the posture information meets a predetermined condition, use the pre-illuminance value as the fusion illuminance value and the pre-color temperature value as the fusion color temperature value; when the posture information does not meet the predetermined condition, The post illuminance value is used as the fusion illuminance value, and the post color temperature value is used as the fusion color temperature value.

Specifically, the embodiment of the present application is described by taking the attitude sensor 60 as a gravity sensor as an example. The attitude sensor 60 is used to obtain acceleration values of the Y axis and the Z axis to determine the inclination angle of the electronic device 100. The predetermined condition may be that the inclination angle of the electronic device 100 is greater than zero. Referring to FIG. 11, when the electronic device 100 rotates clockwise by the angle θ, the posture sensor 60 obtains that the gravitational acceleration value of the Z axis of the electronic device 100 is a negative value, and the value is Z=-g*cosθ, the gravitational acceleration of the Y axis The value is positive and the value is Y=g*sinθ.

At this time, the processor 30 determines that the inclination angle of the electronic device 100 is less than 0, and uses the post-illuminance value as the fusion illuminance value, and the post-color temperature value as the fusion color temperature value.

In some embodiments, determining the fusion light parameters according to the front light parameters and the rear light parameters may also be based on a fusion formula, using the information of the inclination angle of the electronic device 100 to weigh the illuminance value and the color temperature value of the two color temperature sensors, Thus, the fusion illuminance value and the fusion color temperature value of the electronic device 100 are determined. For example, please refer to FIG. 11. When the electronic device 100 rotates clockwise by the angle θ, the inclination angle is θ and is a positive value. Please refer to FIG. 12, when the electronic device 100 rotates counterclockwise by the angle θ, the inclination angle is θ and is negative. value. If the front illuminance value is LuxA, the front color temperature value is CCTA, the rear illuminance value is LuxB, and the rear color temperature value is CCTB, the processor 30 determines the fusion light parameters according to the front illuminance value and the rear illuminance value, and The fusion light parameters can be determined according to the fusion formula: aLuxA+bLuxB=LuxC, cCCTA+dCCTB=CCTC, where the first predetermined coefficient a is a measurement coefficient of the amount of light emitted by the light source 200 received by the front color temperature sensor 10, and the second predetermined The coefficient b is a measurement coefficient of the amount of light emitted by the light source 200 received by the rear color temperature sensor 20. The first predetermined coefficient a may be 0, 0.1, 0.2, etc., the second predetermined coefficient b may also be 0, 0.1, 0.2, etc., and the first predetermined coefficient a and the second predetermined coefficient b may be the same or different. When the light source 200 is on the front 41 of the casing 40 and the inclination angle θ of the electronic device 100 is a positive value and the absolute value is larger, the value of the first predetermined coefficient a is larger, and the value of the second predetermined coefficient b is smaller; when the light source 200 When the inclination angle θ of the electronic device 100 is negative and the absolute value is larger on the back 42 of the casing 40, the value of the first predetermined coefficient a is smaller, and the value of the second predetermined coefficient b is larger. The first predetermined coefficient a is multiplied by the front illuminance value LuxA plus the second predetermined coefficient b is multiplied by the post illuminance value LuxB, and the final fused illuminance value LuxC can be obtained. Similarly, the third predetermined coefficient c is a measurement coefficient of the color temperature value of the front color temperature sensor 10, the fourth predetermined coefficient d is a measurement coefficient of the color temperature value of the rear color temperature sensor 20, and the third predetermined coefficient c may be 0, 0.1, 0.2 etc., the fourth predetermined coefficient d may also be 0, 0.1, 0.2, etc., and the third predetermined coefficient c and the fourth predetermined coefficient d may be the same or different. When the light source 200 is on the front 41 of the casing 40 and the inclination angle θ of the electronic device 100 is a positive value and the absolute value is larger, the value of the third predetermined coefficient c is larger, and the value of the fourth predetermined coefficient d is smaller; when the light source 200 When the inclination angle θ of the electronic device 100 is negative and the absolute value is larger on the back 42 of the casing 40, the value of the third predetermined coefficient c is smaller and the value of the fourth predetermined coefficient d is larger. The third predetermined coefficient c is multiplied by the front color temperature value CCTA plus the fourth predetermined coefficient d is multiplied by the rear color temperature value CCTB to obtain the final blended color temperature value CCTC. Therefore, the processor 30 can obtain the fusion illuminance value LuxC and the fusion color temperature value CCTC, and then control the electronic device 100 through the fusion illuminance value LuxC and/or the fusion color temperature value CCTC.
